LiveNX presents a rich set of real-time diagrams, workflows, and tools to drill down to specific sites, devices or applications to troubleshoot, triage and diagnose complex networking issues.
Historical (DVR) Playback
LiveNX keeps a Data Store of the raw Flow data that allows you to go back in time to replay a flow and watch the transport service across the network for forensic analysis. LiveNX does not average up the data. For other solutions, if you don’t catch the problem soon enough, the data gets rolled up into minute reports which are skewed.
Medianet is the Cisco recommended architecture for video and collaboration deployments. It defines protocols and design practices such as leveraging NetFlow, which LiveNX captures for jitter, latency and voice/video metrics.
LiveNX QoS works with the Cisco Modular QoS CLI (MQC) commands to configure and monitor device QoS settings. Classes define how network traffic should be identified and classified, and which particular QoS actions should be applied to them. The classes themselves are defined as lists of packet-matching criteria. Packet matching can be done through various methods, including NBAR, NBAR2, ACL, and HTTP regular expressions, to name a few. Classes can also refer to other policies that allow the creation of hierarchical policies several levels deep.
Application Visibility and Control
Cisco Application Visibility and Control (AVC) is a solution that uses multiple technologies such as NBAR2 and NetFlow version 9 and management tools that, when working together, provides a powerful and pervasive integrated solution for application visibility.
Deep Packet Inspection
Deep packet inspection (DPI) is a networking technology that enables the capture and inspection of the data portion of a packet.
LIveAction and Savvius announced a strategic partnership. LiveAction boosts network performance by proactively spotting potential issues, providing analytics into network traffic flow and offering historical playback of network activities to reenact a point of failure from any time. Savvius complements LiveAction’s LiveNX platform by further diagnosing the source of complex infrastructure and application problems through continuous packet capture, micro-level network visibility and forensics, operations analytics, and cyber surveillance of users, infrastructure, applications, and services.
The LiveNX Flow technology module provides an innovative network topology view with end-to-end NetFlow, sFlow, and J-Flow visualizations of live traffic across the network. This enables you to quickly drill down to individual devices or interfaces for more detail on flow characteristics such as IP addresses, DSCP values, byte rates and count. In addition, the LiveNX Flow technology provides historical and real-time reporting, filtering, flexible support for different templates and many other features, which makes it easy identify trouble spots on the network and gain a better understanding of traffic patterns.
LiveNX provides many capabilities for managing QoS policies. It utilizes a rule-based engine that performs policy management based on the current state and configuration of the device, and intelligently applies commands to resolve any conflicts or to warn of any conflicts.
An analytics node is a software that collects data to be sent to LiveNX Insight for analysis. It is deployed as an OVA typically co-located with the LiveNX Node.
Network-Based Application Recognition
NBAR and NBAR2 are Cisco Deep Packet Inspection (DPI) technology. Network-based application recognition (NBAR) is a way of inspecting streams of packets, down to layer 7 inspection, to identify the end application. NBAR2 provides stateful Deep Packet Inspection (DPI) capability natively. NBAR, or NBAR2 support over 1000 applications signatures.
